Title: Oxidation process
IPC: C01B17/06
Filed: 1970-09-10
Abstract: 1321295 Oxidation of metal-sulphur compounds MOLYBDENUM CORP OF AMERICA 10 Sept 1970 [11 Sept 1969] 43325/70 Heading C1A A metal sulphide compound selected from the sulphides of Mo, V, W, Sn, Sb and the alkali metal salts of said sulphides is oxidized to obtain metal oxides and sulphur by subjecting it in aqueous medium to elevated temperature (60-200 C.) and pressure (50-600 p.s.i.a.) in the presence of a free oxygen-containing gas, The composition is treated in aqueous solution or as a slurry. The preferred duration of oxidation stage is 15 mins to 12 hours, the quantity of free oxygen containing gas used should be sufficient to supply a stoichiometric amount of oxygen for complete oxidation of the metal-sulphur composition. The oxidation product, consisting of metal oxides and sulphur may be filtered and the filter cake extracted with ammonia solution to dissolve metal oxides and leave elemental sulphur. Metal oxides are then recovered by evaporation of the solution and calcining. Alternatively the metal component may be recovered by solvent extraction followed by filtration and evaporation. The metal sulphide compound may be obtained by mixing an alkali metal sulphate with a metal concentrate in a molar ratio of at least 1À5 : 1, heating to 700-1600 C. in a non oxidising atmosphere and contacting with an aqueous leach solution to dissolve the alkali metal salt of metal sulphide, separating this salt from the insoluble residue and liberating metal sulphide by addition of mineral acid.

Title: Gating Oscillator Circuits

IPC: H03K17/73
Filed: 1965-10-28
Abstract: 1,161,315. Triggering controlled rectifier. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 13 Oct., 1966 [28 Oct., 1965], No. 45717/65. Heading H2F. [Also in Division H3] A control circuit for a controllable rectifier including means responsive to a control signal input and the phase of an alternating current supply also supplied to the rectifier to generate a keying signal for an oscillator to generate a drive signal for the rectifier, includes an oscillator provided with switching means adapted to interrupt a feedback path or a power supply to prevent the oscillator being triggered by transients in an output circuit. In Fig. 1 the blocking oscillator VT4 includes a normally non-conducting transistor VT3 in its feedback path. When the normally conducting transistor VT2 is cut off by an input signal, VT3 conducts and a train of output pulses is produced. In a modification, Fig. 2 (not shown), VT2 is omitted and the input signal is applied through a resistance to the base of VT3. In another arrangement, Fig. 3, the blocking oscillator VT7 includes a normally non-conducting SCR in the lead from the power supply to its collector so that it does not oscillate until SCR is triggered and a drive signal is applied to its base. Drive circuit, Fig. 3.-An A.C. input at terminals 1 and 2 maintains VT1 conducting except at the zero crossings; at these instants a negative pulse is applied to the monostable circuit VT2, VT3 which removes the bias from MR8 and allows capacitor C5 to discharge through R14. After the monostable circuit has timed out, the timing capacitor C5 charges through VT4 until VT4 cuts off at a point determined by an input voltage on terminals 3 and 4. This removes the drive to VT5 via Zener diode MR14 so VT5 cuts off and applies a trigger pulse to SCR. After a delay of about 100 microseconds caused by C6 and R20, a drive pulse is applied from VT4 to the base of VT7 to initiate oscillation. When the transistor VT3 of the monostable circuit becomes non-conducting, C2 becomes charged and provides base drive for VT1 for a predetermined time somewhat less than one half-cycle of the supply waveform. During this time the occurrence of a spurious zero in the supply at terminals 1 and 2 does not render VT1 non- conducting.

Abstract: 1480300 Telegraphy; signalling by DC; transistor switching circuits ING C OLIVETTI & CO SpA 10 Nov 1975 [24 Dec 1974] 46425/75 Headings H4P and H3T  In a teleprinter double current line switching  unit comprising transistors connected to provide positive and negative voltages through a line isolating circuit, a delay network is provided so that one polarity transistor turn on is delayed to allow for transit time recovery of the other polarity transistor to its blocked state. A protective circuit also temporarily blocks a presently conductive transistor if line current exceeds a determined value. Data signals from G pass through inverting amplifier 5 and R.C. delay network 35, 36 (say 20 Á.sec) to squaring amplifier 6 controlling, through opto-electric device 18 and a driving amplifier including transistor 41, line transistor 21. Delay in circuit 11 affects falling edges of data signals (M) hence delays turn on of transistor 21. Protective circuit 32 comprises transistors 51, 52 connected in "SCS" configuration. A line short circuit causes increased flow in resistor 27 which is applied to base of 21 thus blocking it. Also increase of voltage across resistor 27 causes saturation of transistor 51 which in turn saturates 52 consequently maintaining 21 blocked until the next data signal of opposite type appears. Similarly data signals through inverter 12 control a corresponding circuit for the opposite polarity. In this circuit part the delay affects the falling edges of (M) inverted, i.e. the rising edges of (M) and delays turn on of opposite polarity transistor 26.
